Embodiment 1
[0029] This embodiment provides a synthesis method of CuS hollow nanomaterials, and the specific synthesis steps are as follows:
[0030] One, the preparation of copper methacrylate:
[0031] Put 0.1 mol of copper oxide and 0.2 mol of methacrylic acid into a single-necked round-bottomed flask filled with 200 ml of high-purity water in turn, react in a water bath at 50 °C for 24 h, filter to obtain a blue clear solution, and place it in an Erlenmeyer flask spare. Take 30 mL of the solution in a beaker, add 30 mL of absolute ethanol, let it stand for 3 h, centrifuge the precipitate at a rate of 4000 r / min, remove the supernatant to obtain a blue powder, wash it repeatedly with absolute ethanol for 2~ 3 times, dried in a vacuum oven for 6 h, and weighed.
[0032] 2. Preparation of CuS hollow nanomaterials:
[0033] The same mass of thiourea as the dry powder was dispersed in 30 mL of absolute ethanol. In order to achieve the high pressure required for the reaction, it was vulc...
Embodiment 2
[0040] This embodiment provides a synthesis method of CuS hollow nanomaterials, and the specific synthesis steps are as follows:
[0041] One, the preparation of copper methacrylate:
[0042] Put 0.1 mol of basic copper carbonate and 0.2 mol of bromoacetic acid into a single-necked round-bottomed flask filled with 200 ml of high-purity water in turn, react in a water bath at 50 °C for 24 h, filter to obtain a blue clear solution, and place it in an Erlenmeyer flask in spare. Take 30 mL of the solution in a beaker, add 60 mL of absolute ethanol, let it stand for 3 h, centrifuge the precipitate at a rate of 4000 r / min, remove the supernatant to obtain a blue powder, wash it repeatedly with absolute ethanol for 2~ 3 times, dried in a vacuum oven for 8 h, and weighed.
[0043] 2. Preparation of CuS hollow nanomaterials:
[0044] Disperse the same mass of dry powder and thiourea in 60 mL of absolute ethanol, and vulcanize for 6 h at 50 °C in a polytetrafluoroethylene reactor wit...
